Zoe is solving the equation 3x – 4 = –10 for x. she used the addition property of equality to isolate the variable term as shown.3x – 4 = –103x – 4 + 4 = –10 + 43x = – 6which two properties of equality could zoe use to finish solving for x? either the addition or subtraction property of equalityeither the multiplication or division property of equalityeither the addition or division property of equalityeither the subtraction or division property of equality

The given equation is

To isolate the variable x, first we have to do addition. And the ruleis addition postulate.

Now we need to get rid of 3, and for that, we have to divide both sides by 3. And the postulate is division postulate.

So the two properties are addition and division .

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
